lMPROVEMENT m HOSE PORT-HOLES FOR PARTITION-WALLS.

Specification forming part of Letters Patent No. 136,687, dated March11, 1873.

To all whom it may concern:

Be it known that I, HENRY WOODMAN, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and useful Improvementin Hose-Nozzle Port-Hole for Partition-\Valls, of which the following isa specification:

Figure 1 is a detailed horizontal section of my improved device takenthrough the line as .10, Fig. 2. Fig. 2 is a detail vertical section ofthe same taken through the line 3 3 Fig. 1.

Similar letters of reference indicate correspondingparts.

My invention has for its object to furnish an improved device to enablethe firemen to introduce their hose-nozzle into a closed room and floodit to extinguish a fire without its being necessary to break into theroom, saving much time, and preventing the fire from making so muchheadway. The invention consists in the box flaring in both directions,the perforated partition, the hinged doors, the locks, the inner hingeddoors, and their springs with each other, to adapt the device for use,as hereinafter fully described.

A is a box, made in the shape of two hop- .pers, placed with their smallends toward each other, and with a partition, B, across their middle ornarrowest part. The mouths of the box A are closed with doors 0, hingedat their lower edges to the said box, as shown in Figs. 1 and 2. Thedoors() are provided with spring catch-locks D, which can be opened uponthe outer side only with a key, but may be unlocked from the inside by.drawing back the bolt of the lock with a stick or other convenientmeans. For convenience in doing this a projection, 12, is formed uponthe inner end of the bolt of the look. In the partition B are formed twoor more holes, each of which is provided with a door, E, which doors areplaced upon the opposite sides of said partition B, and are hinged attheir outer edges to the sides of the box A. The doors E are providedwith springs F to hold them closed.

The device is designed to be made of such a size that when built intothe wall its doors 0, when closed, may be flush with the oppositesurfaces of said wall. When it becomes necessary to use the device thedoor 0 is opened, one of the spring-doors, E, is then opened, a stick orother article is inserted through the hole in the partition B, and theother door is opened by drawing back the bolt of its lock D by means ofthe'projection (1 upon the inner end of said bolt. The nozzle of the.hose may then be inserted through one of the holes in the partition B.One of the holes in the partition B may be used to look through whilethe hose-nozzle is inserted through the other, the flaring mouths of thebox A enabling all parts of the room to be seen, and the stream of waterto be ,directed to any desired point. When the room has been flooded orthe fire extinguished the hose-nozzle may be withdrawn, and the door 0closed, the door E closing itself as soon as the hose-nozzle iswithdrawn.

The box A may be made with straight instead of flaring sides, ifdesired; but I prefer the flaring construction, as giving a moreextended view of the interior of the room.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of the box A, the perforated partitionB, the hinged doors 0 provided with locks D d,hinged doors E, andsprings F with each other, to adapt the device for use, substantially asherein shown and described, and for the purpose set forth.

HENRY WOODMAN.
